Abstract

A method of reading data (DAT1..DAT4) from transponders (T1..T4) by means of a reader device (RD) during a number (N) of time slots (TS) is disclosed, wherein the seizure of said time slots (TS) by the transponders (T1..T4) is observed in both the reader device (RD) and the transponders (T1 ..T4). A reorganization (REORG) is performed in dependence on said seizure, wherein both the reader device (RD) and the transponders (Tl ..T4) choose a new number (N) of time slots (TS). In addition, the transponders (T1..T4) select one of the new time slots (TS) in which to send data (DAT1..DAT4) back to the reader device (RD) so as to adapt the system's capacity to the real demands. Preferably, said reorganization (REORG) takes place without communication between the reader device (RD) and the transponders (T1 ..T4). The invention further relates to a transponder (T1..T4) and to a reader device (RD) for implementing the inventive method.
